Isothermal Bomb Caloriemeter BCM-P

+ Know More


This is additionally provided with a Automatic Gas Filling Adaptor which simplifies the Oxygen filling procedure. The valve opens and allows filling of Bomb with Oxygen because of Oxygen pressure for cylinder. It closes when pressure from Oxygen Cylinder is cut off.
Our latest design of easy to use Gas Filling System greatly reduces of damage to the costly Gas Filling Tubes with our latest design of Stainless Steel braided PTFE Hose. Our tests have indicated that this new Gas Filling System reduces the time taken for Oxygen charging from around 10-13 minutes (using the copper tube) to less than 3 minutes (using the new Gas Filling System) while simultaneously avoiding chances of cross-threading & subsequent damage to the Gas Filling System.
Each Advance Calorimeter Bomb is tested thoroughly before it leaves the factory at internal pressure of 300kg/cm2 for a period of 10 minutes without any sign of leakage in accordance with requirements of the Institute of Petroleum (I.P. 12/58T, Appendix I), IS:1350 (Part-II) 1970 and works Test certificate issued with each Bomb.
